It is often referred to as the false widow, although "false widow" is a more general term applied to a wider group of species with this resemblance. [3] It is a moderately medically significant spider, with most bites resulting in symptoms similar to a bee or wasp sting. [4]
Unlike most species of widow spider, which are dark in colouration; the white widow spider is, as its name implies, light-coloured, with colouration ranging from beige to white, though with darker legs. The spider lacks the bright red markings found on other widow spiders such as the black widow, the redback spider, or L. tredecimguttatus ...
A bite of Latrodectus may not inject any venom (known as a dry bite) and so no illness occurs. About 75% of "wet" bites will have localized pain and nothing more. [1] If, however, there is a substantial dose, a bite can cause latrodectism. The main symptoms are generalized muscle pain, stomach cramps, nausea and vomiting.
The symptoms associated with the bite of several Steatoda species have been named steatodism; and have been described as a less-severe form of latrodectism (the symptoms associated with a widow spider bite). The redback spider antivenom has been thought to be effective at treating bites from S. grossa, after it was mistakenly administered to a ...
The white-tailed spider (Lampona) was implicated for decades in necrotic lesions, but has been exonerated. [3] A study of 130 white-tailed spider bites found no necrotic ulcers or confirmed infections; only a red mark, local swelling, and itchiness. Very occasionally nausea, vomiting, malaise or headache may occur. [51]

When a widow spider is trapped, it is unlikely to bite, preferring to play dead or flick silk at the potential threat; bites occur when they cannot escape. [20] Many injuries to humans are due to defensive bites delivered when a spider gets unintentionally squeezed or pinched.
